Composition/Operation
Duplex Option
• Steps 6 through 8 are repeated.
Operation 5
• While feeding the first 2-sided print out, main unit produces
the print image of the 6th page of the original on the third
sheet of paper.
• The second sheet of paper waits at the duplex take-up
position until the third sheet of paper is subjected to a
switchback sequence.
